Describe the bug

#107 added support for custom postgres types. The problem is the type is added outside of the normal migration, which is a problem if said column is also in an index on the table

To Reproduce

1. Create table with column that is a type, but which also has an index on that column
2. Generate migrations

This will create a migration ala

public function up()
{
    Schema::create('table', function (Blueprint $table) {
        ...

        $table->index(['column']);
    });
    DB::statement("ALTER TABLE table ADD column custom_type NOT NULL");
}

Which will fail since column is not defined when the index is added
